Hydrocarbons exist in abundant quantity beneath the earth's surface. These hydrocarbons
are generally classified as conventional and unconventional hydrocarbons depending upon …

Tight oil reservoirs are contributing a major role to fulfill the overall crude oil needs,
especially in the US. However, the dilemma is their ultra-tight permeability and an …

In recent times, particularly in the 21st century, there has been an alarming increase in the
demand for global energy, along with continuous depletion in conventional oil reservoirs …

In this paper, we propose a novel analytical solution to predict the diffusion coefficient and
depth of natural gas penetration during soaking period of the cyclic gas injection process …

The drive for capital efficiency in unconventionals has encouraged operators to understand
subsurface interactions as effectively as possible. Combining multiple types of new and …

In this paper, the sensitivity factors of CO2 huff‐n‐puff for multifractured horizontal wells
(MFHWs) in tight oil reservoirs were investigated through an experimental test and …

Abstract Gas Huff-n-Puff (HnP) has been implemented as an enhanced oil recovery
technique to recover the residual oil after primary production from unconventional wells …

Carbon dioxide injection in shale reservoirs can be beneficial for enhanced oil recovery and
CO2 storage scenarios. CO2 mass transfer can be influenced strongly by the in-situ …

Unconventional oil wells exhibit rapid decline in oil production rate and low ultimate oil
recovery, even though the lateral drilling and completion technology have advanced …

Cyclic injection-flowback (huff and puff, HnP) of natural gas or carbon dioxide has been
shown to improve the recovery of oil from low permeability, low porosity shale reservoirs …
